SPECIFICATION forming part of Letters Patent N 0. 769,778, datedSeptember 13, 1904.

Application filed February 9, 1901. Serial No. 46,648.

To all whom, it may concern:

Be it known that I, JOHN D. STIROKLER, a citizen of the United States.and a resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented a new and useful Improvement in SocketMembers, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings,forming a part of thisspeci- IO fication, in explaining its nature.

The invention relates to the herein-described improvement insingle-piece socket members of ball-and-socket fasteners.

It comprises a hollow structure having be- 5 fore it is set to materiala continuous top which corresponds to the part of a fastener known as acap and which extends over the socket-entrance and over the flange tocover and conceal both, a flange which bears against a surface of thematerial to which the member is set, and a tubular extension from saidflange having longitudinal slits or openings in it, not, however,extending through the lower edge or into the flange unless desired, and5 which tubular extension is adapted to be passed through a hole inmaterial to which the socket member is secured and in the act of settingor securing the member to then be formed to provide a socket-entrancesubstantially upon 3 a line with the surface of the material oppositethat upon which the preformed flange bears, and a continuous innerfastening-flange extending from the socket-entrance upon the innersurface of the said material. Referring to the drawings, Figure 1 is aView in elevation of a socket-piece. Fig. 2 is a view in verticalsection of a socket-piece and of material, the socket-piecebeingassembled with the material, but not being set. Fig. 3 4 is a viewin section of the set socket-piece or socket member and the material.Fig. A is a View in plan, inverted, of the socket member and material.Figs. 5, 6, and 7 represent a modified form of socket-piece and socketmember to which reference will hereinafter be made.

Referring to the drawings, a represents the top upper surface or cap ofthe member. It

(No model.)

is of any desired configuration, is preferably continuous, and is notchanged In shape mate- 5 .rially, if at all, in the act of setting. Itcovers the flange b and the socket-cavity 0. The flange Z; is integralwith the cap a and and has a tubular extension (Z, provided with thelongitudinal openings 0, which may be confined to a portion of thetubular extension, as represented in Figs. 1 and 2, or which may bearranged as shown in Figs. 5 and 6. The lower edge f of the tubularextension is continuous and is scalloped, as represented. The tubularextension preferably is offset, as represented in the figures, and theshoulder thus formed in the set socket-piece or socket member forms theedge about the socket-entrance and an enlargement within said edge. Theoifset is oh- 5 tained by making the upper part ofthe tubular extensionlarger in diameter than the lower part. An unset socket member of thisstructure lends itself readily to a transformation in the act of settingto material, whereby a socket- 7 O entrance 9 is formed, the cavity 0above or within the socket-entrance established, and an innerfastening-fl ange it, continuous at its outer edge, obtained. Such asprocket member may be used with a resilient ball member or not, asdesired. If the ballmember is not resilient, it will be desirable,though not necessary, to use longer openings 0 in the tubular extensionthan would otherwise be used. By making the lower edge of the tubularextension scalloped 30 provision for the change in the disposition ofthe metal from the tubular form to the flat form of a continuous flangeis secured. By extending the slits or openings 6 to or into the scallopsthey may be made longer than if they 5 are extended radially toward thepoints between the scallops, and hence will'serve more surely thepurpose in forming the flange per-- tion of the set device of allowingthe material of this portion of the device to adjust itself 9 accordingto the conditions of its use.

The structure shown in Figs. 3 and 4 is adapted to be used with ayielding ball member and the structure of Figs. 6 and 7 with anunyielding ball member.

Having thus fully described my invention,

I claim and desire to secure by Letters Patent of the United States 1. Asocket-piece of a ball-and-socket fastener made from one piece of metaland having a preformed cap, a folded flange, and a cylindrical extensionfrom the inner end of the flange of two diameters, the section of saidcylindrical extension nearest the flange being of a larger diameter thanthe outer end of said cylinder and forming with said outer end ashoulder at the socket-entrance, the said outer end section being of alength to form when upset an inner fastening-flange, and also havingslits which may extend into the shoulder and which do not extend throughthe end of said cylindrical section, whereby the smaller cylindricalsection may be folded outwardly to form a fastening-flange having acontinuous edge and a socket-entrance immediately below said shoulder.

2. A socket-piece of a ball-and-socket fastener made from a single pieceof metal having a cap, a flange, a tubular extension from the flangehaving a continuous scalloped edge and slits in said tubular extensionextending to or into said scallops, whereby a portionof said cylindricalextension may be folded? from a cylindrical form to the form of a foldedfastening-flange at a right angle to the cylindrical section and with acontinuous outer edge, said slits allowing the material of said flangeto adjust itself during the process of folding to allow. said flange tolie substantially flat against the fabric.

3. A socket member of a ball-and-socket fastener made of a single pieceof metal and having a cap, an upper retaining-flange, a tubular bodyabruptly contracted at its lower end or throat, and a radially-slitted,lower retaining-flange having a continuous outer edge, the upperretaining-flange being continued at its outer circumference into the capand at its inner circumference into the tubular body, and the tubularbody being continued at the throat into the lower retaining flange.
